Cold Spring Harbor Protocols Features Drosophila Neurobiology Methods

07/01/2010

COLD SPRING HARBOR, N.Y. (Thurs., July 1, 2010) – Since the early days of the 20th century and Thomas Hunt Morgan's famous "Fly Room" at Columbia University, the fruit fly Drosophila melanogaster has been at the forefront of biological research. The powerful arsenal of experimental methods developed for this model organism is now being used to tackle one of the great scientific challenges of a new century: understanding the nervous system. Cold Spring Harbor Laboratory's Neurobiology of Drosophila course (http://meetings.cshl.edu/courses/c-dros10.shtml ) has served as the training ground for a generation of scientists tackling these complex problems. A new laboratory manual based on the protocols and background information taught in the course ( http://www.cshlpress.com/link/drosneurop.htm) promises to spread these techniques to a wider audience. Two of the methods from the manual are featured in the July issue of the journal Cold Spring Harbor Protocols (http://cshprotocols.cshlp.org/TOCs/toc7_10.dtl ).

The larval Drosophila brain has been a valuable model for investigating the role of stem cells in development. These neural stem cells, called "neuroblasts," have provided insight into the role of cell polarity in influencing cell fate. Identifying neuroblasts and their progeny requires a method capable of recognizing cell polarity and cell fate markers. Immunofluorescent Staining of Drosophila Larval Brain Tissue, provided by Cheng-Yu Lee and colleagues (http://www.lsi.umich.edu/facultyresearch/labs/lee ), describes procedures for the collection and processing of Drosophila larval brains for analysis of these markers. Neuroblasts are identified via immunolocalization, the use of labeled antibodies that specifically bind the marker proteins of interest. The article is featured in the July issue of Cold Spring Harbor Protocols (http://www.cshprotocols.org/TOCs/toc7_10.dtl ) and is freely available on the journal's website (http://cshprotocols.cshlp.org/cgi/content/full/2010/7/pdb.prot5460 ).

About Cold Spring Harbor Protocols:Cold Spring Harbor Protocols ( www.cshprotocols.org ) is a monthly peer-reviewed journal of methods used in a wide range of biology laboratories. It is structured to be highly interactive, with each protocol cross-linked to related methods, descriptive information panels, and illustrative material to maximize the total information available to investigators. Each protocol is clearly presented and designed for easy use at the bench—complete with reagents, equipment, and recipe lists. Life science researchers can access the entire collection via institutional site licenses, and can add their suggestions and comments to further refine the techniques.

About Cold Spring Harbor Laboratory Press: Cold Spring Harbor Laboratory Press is an internationally renowned publisher of books, journals, and electronic media, located on Long Island, New York. Since 1933, it has furthered the advance and spread of scientific knowledge in all areas of genetics and molecular biology, including cancer biology, plant science, bioinformatics, and neurobiology. It is a division of Cold Spring Harbor Laboratory, an innovator in life science research and the education of scientists, students, and the public. For more information, visit www.cshlpress.com .
